Handling Back Button Press during Transition of an Activity which uses Animation

Back Button Navigation problem: when pressing Back button while the activity is getting animated, if the back button is pressed, it will to navigate to previous activity twice. How to resolve it?

This is our Code

    final Intent intent = new Intent(getApplicationContext(), DrugHelp.class);
    ActivitySwitcher.animationOut(findViewById(R.id.container),getWindowManager(),
                new AnimationFinishedListener() {
                @Override
                public void onAnimationFinished() {
                startActivity(intent);
                finish();
                }});

if it is just previous activity you are launching in side onAnimationFinished, then don't call startActivity, just finish the current activity only

I assume DrugHelp was the Activity previous to this one. It was probably never finished so it is still on the stack. If this is the case, simply finishing this Activivty will take you to the previous one that hasn't been finished. You can also use Intent Flags to bring that one to the front of the stack if it already exists.

final Intent intent = new Intent(getApplicationContext(), DrugHelp.class);
intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

You also could use Intent.FLAG_ACTIVITY_CLEAR_TOP if you want to make sure that all other Activities on the stack are taken off.

ReorderToFront

Other intent flags

Try this:

public void onBackPressed() {
   this.finish();
}

If it still go back twice, set a boolean to true when you're starting your animation, and in the function above, add

if(!yourBoolean){
   this.finish();
}

Hope this help.
